y application filed Julyja,

, The present invention has relation to ad- ,justers yory devices employed 'for retaining a door, window or thek likein a 'iull open or intermediate open positions.,r The object. ot' ctheinvention, among other things, is to v produce an etiicient device which is simple,

@both in` construction and roperation and because of itsusimplicity, the costei producktion 1s materially decreased and the device may be easily installed by even an ineXpe f Heretofore various kinds o1 devices have vious devices in that the rdevice so con structed and arranged that it is seltacting so as to lock ltsell' in the open position oit the door. To release the device only` an `initial operation is required to effect the` release and the door or window ymay then be closed withoutfurther attention to ther adjuster. y f f j The. improved device is designed more particularily for-garagedoors and willbe hereinafter described being so applied, and I further, an. embodiment of the `inven- `tion will be described with reference to the accompanying drawings, wherein Figure 1y is a perspective view showing the improved device in the position for use;

Figure lis a longitudinal,sectional view of the improved device; c

Referringto the said drawings, 1 represents a bar which ispreferably composed of tubing, 2 is a bracket which is secured to the underside of the lintel oil' the door and 3' is another bracket which is secured directly to the door. It will be understood that the invention is shown in connect-ion with a garage doorv and as usual, double doors are employed. therefore an adjusting device is provided for each door or section.

The bar or member 1 as stated, is comi926. serial 110.121,310.

posed oit tubing and has one end 1 cut out "and 'iliattened so'asto provide an extended bearing. The opposite end of the tubing is cut out so asy to form a projection which ,bent upwardly to torni a tongue orstop 5. A notch 6 is eut in theunderside ot' the tubing diainetrically opposite to the tongue l 5. `The bracket 2 has erosspieces7 and 8 and vertical sides 9 and between said cross andvertical pieces, an open recess is formed in which the member 1 is adapted to slide.

rlheflattened out end t of the bar '1 provides'ithe bearing on whichihe said bar swings from a/center provided by the' pintle 10 which preferably tapered andrpasses through a hole 11 in the `flattened end l and another hole inthe portion of the bracket 3 which extends at right angles to the main portion oi the bracket which is secured to the door. Obviously an ordinary bolt may be used instead of the pintle asr shown and in which case the holes through which the bolt passes'would be ofgreater diameter than the bolt so as to allow play thereby perr-k nritting 'the bar 1 to readily assume an an- "gular position relatively to its supporting bracket 3. kSaid pintle or bolt has an en-` larged head 12 and a coiled spring 13 surrounds said bolt or pintle. Chain 14 connected to and depending from bar 1 provides means whereby the bar is turned to release the device. g 1 y ln the operation of the device, the door is brought to its openfposition without any releasing of the device and the bar will slide within the recess oit bracket 2 until the notch 6 engages `the cross piece 8 ott bracket 2. It noy intermediate stop is required, tho door will open to its t'ull extent andthen the ynotch at rthe end of rthe bar willbe engaged, rthe engagement being effected by gravity. `When it is desired to close the door, the chain 14 is pulled and this gives the bar a quarter turny so that the notch or notches (Slat the side of the bar are disengaged and in this 'position ythe said bar will be allowed to slide tothe position it is in when the door is closed. The spring bearing device for the ybar is provided 'for several purposes, one is the bar is turned to an angular position, said shown and consist bar rests on one edge and has the tendency therefore to return to its normal position, in which the notches 6 are in the position for engagement. The hook or tongue on the end of theY rod serves as a stop to prevent the bar l from being pulled out of itsl supporting bracket.

In Figures 3 and L modifications are of'plugs l5, preferably cast iron7 adapted to be insertedL into t-he ends of the tubing and are held therein by means of pins 16. One et these plugs has the notches 6 and the lip or projection 5 and the other plug has the flattened bearing. The advantages ot the modiiied forms are mainly in connection with the manufacture of the improved device. tshould however, be noted in Figure 3, the plug has only a shoulder l? instead of the notch previously described. This shoulder, in conjunction with the projection Will serve to retain the device in its engaged position with the bracket 2.

Other modifications of the invention, both as regards construction and application may be made Without departing from the spirit of the invention and it is to be understood any modilication coming fully within the terms of the appended claims shall be covered thereby.

I claim- Y l. All adjuster' o the class described having a bar held in its normal or engaging position; by gravity.. a loose rocking pivotal connection for said bar, an engaging support t'or the free e-nd ot' said bar and means for releasing said bar from its engagement With said support.

An adjuster of ther class described having a bar held in itsnormal or engaging position by gravity, a loose rocking pivotal connection for said bar comprising a Vfiattened end et' said bar a bracketand a pivotal pin, a spring interposed between said pin and said` bracket` an engaging support `tor the free end of said bar and means for releasingA said bar from its engagement with. said support.
